Force India technical director Andy Green has revealed his team is now focusing its development resources on next year's car.

Force India is currently eighth in the standings but has scored 20 more points this season than it had at the same time last year.

"Development now really is turning to next year," Green said at the Hungarian Grand Prix. "For a team of our size we can't afford to develop a car much beyond this point in the season. It's really a case of trying to optimise what we have."

The team started the year aiming for fourth in the constructors', but after a much more open season than usual it is now setting its sights on beating Sauber and Williams to sixth.

"At the moment we would be targeting sixth position, that would be a realistic target for us," Green added. "It's going to be difficult. The cars in front of us are all very, very competitive. So it's going to be a big ask and we'll have to dig deep, as we always do, and we'll be pushing like crazy right until the end. That'll be the plan and we'll see where we finishing.

"So far we're in a position where we're better than we were last year with respect to points and we're reasonably happy with that. If every race we score more and more points then ultimately we're going to go up. But there are just some teams in front of us who have scored some big results and got on the podium and that's put us behind them. It's just a matter of chipping away at them and hopefully by the time we get to the end we'll be just in front. That'll be the plan."
